This phase II trial studies how well radiation therapy works when given with gemcitabine
hydrochloride and cisplatin work in treating patients with squamous cell cancer of the vulva
that has spread from where it started to nearby tissue or lymph nodes. Specialized radiation
therapy that delivers a high dose of radiation directly to the tumor may kill more tumor
cells and cause less damage to normal tissue. Drugs used in chemotherapy, such as gemcitabine
hydrochloride and cisplatin, work in different ways to stop the growth of tumor cells, either
by killing the cells, by stopping them from dividing, or by stopping them from spreading.
Giving radiation therapy together with gemcitabine hydrochloride and cisplatin may kill more
